Energy market analyst Bentek Energy said the results of their latest study show that reductions of carbon dioxide emissions from the wind energy sector were either minimal or too expensive to be practical.

The group’s president Porter Bennett said that Bentek Energy had made use of actual hourly wind generation and emissions data to test the hypothesis that wind energy was an effective tool to control carbon dioxide and other air emissions.

The group said that they were the first to systematically assess the emission reduction performance of wind generation based on the two data.

“Policy makers should take note: the actual emissions data over a three-year period refutes these claims. This report requires reassessment of wind as an emission control strategy,” Mr. Bennett said.

The study consisted of more than 300,000 data points, including actual wind, coal and gas generation and emissions data during the past three years. All emissions data were taken directly from the Environmental Protection Agency, while wind generation data comes from plants in four regional power areas across the United States.
